Claims (1)
閉弁と、前記供給通路に接続された複数の切換弁
と、前記切換弁を個々に切換えるパイロツト弁と
、制御する負荷が軽い切換弁と前記供給路の間に
設けた可変絞り弁と、制御する負荷が重い切換弁
に関わるパイロツト回路の最高圧力を選択して前
記可変絞り弁に作用させる１以上の選択弁と、前
記選択弁群に付加し全切換弁のパイロツト回路の
最高圧を選択して前記開閉弁に作用させる１以上
の選択弁よりなる制御弁装置。 An on-off valve interposed between a supply passage connected to a hydraulic power source and a tank, a plurality of switching valves connected to the supply passage, a pilot valve that switches the switching valves individually, a switching valve with a light load to control, and the supply. a variable throttle valve provided between the valves, one or more selection valves that select the maximum pressure of a pilot circuit related to a switching valve with a heavy load to be controlled and act on the variable throttle valve, and a selection valve added to the selection valve group. A control valve device comprising one or more selection valves that select the highest pressure in a pilot circuit of a full switching valve and apply it to the on-off valve.
